You can take a bath 20 days after the cesarean section if your body recovers well and your mental state is fine. But when you take a bath, you should pay attention to the following points: 1, take a hot bath. 2, take a shower, not a sitz bath, because a sitz bath may cause the bath water to enter into the vagina, and then enter into the uterine cavity and cause infections, because the uterine local incision is not completely healed at this time, and the wound is easy to get infected. 3, it is best to have someone accompany you when taking a bath, so as to avoid the occurrence of the eventuality. 4, take a bath and wipe it dry with a towel quickly. After the bath, quickly dry with a towel, pay attention to warmth, wear long clothes and pants in time, and then give rest, the above is more than 20 days after the cesarean section can take a bath, but the matters to be paid attention to.
